Description
本発明は、塩化メチレンを含まない塗膜剥離用軟化剤を使用した圧縮エアと高圧水の混気ジェット噴流による洗浄方法に関する。 The present invention relates to a cleaning method using a mixed jet jet of compressed air and high-pressure water using a softener for removing a coating film that does not contain methylene chloride.
従来から建築構造物等の維持・保全には、躯体の仕上塗装の剥離再生が必要不可欠となっている。また、建築構造物等の外壁の改修工事を行う際に塗膜を剥離する方法としては、剥離剤を塗布した後、スクレバー等で除去する方法が知られている。 Conventionally, it is indispensable to remove and refinish the finishing paint of the frame for maintenance and maintenance of building structures. In addition, as a method of peeling a coating film when repairing an outer wall of a building structure or the like, a method of removing with a scrubber after applying a release agent is known.
しかし、従来の剥離剤による除去方法は、人体にとって有害性が皆無でない塩化メチレン（ジクロロメタン）を使用しているため、環境保全等の観点からその使用を抑制する方向にある。また、洗浄水は排水処理が必要となり、酸及びアルカリ性の廃水は中和してから排水しなければならない。 However, the conventional removal method using a release agent uses methylene chloride (dichloromethane), which is not harmful to the human body, and therefore tends to suppress its use from the viewpoint of environmental protection. In addition, the washing water needs to be drained, and the acid and alkaline waste water must be neutralized before being drained.
上記の問題の解決を図るため、塗膜を溶解せず軟化させる塗膜剥離剤工法の先行技術として、特開平１０−３３１４３５号公報（特許文献１）に、環境破壊や公害につながらず、動植物に対してもやさしく、安全面や衛生面にも支障のない剥離剤を用い、かつ下地を必要以上に傷めることのない建築構造物等の塗膜剥離剤工法を提供することを目的とし、被剥離対象物の塗膜面に、生分解性（土中微生物分解性）剥離剤溶液を適宜の手段で塗布して塗膜を軟化・膨潤させ、ノズルから吐出する高圧温水を塗膜面に噴射させることにより塗膜を剥離する「塗膜剥離剤工法」が提案されている。 In order to solve the above problems, as a prior art of a coating film peeling agent method that softens a coating film without dissolving it, JP 10-331435 A (Patent Document 1) does not lead to environmental destruction or pollution, The purpose is to provide a coating film peeling agent method for building structures, etc. that uses a peeling agent that is safe and hygienic and that does not damage the ground more than necessary. Apply biodegradable (soil microbial degradability) stripper solution to the surface of the object to be peeled by appropriate means to soften and swell the film, and spray high-pressure hot water discharged from the nozzle onto the surface of the film. There has been proposed a “coating film removing agent method” in which the coating film is peeled off by applying the coating film.
一方、本願発明者が開発した圧縮エアと高圧水の混気ジェット噴流による直接洗浄を行う除去手段を用いた洗浄方法として、特開２００７−９２３８７号公報（特許文献２）には、建築物の建材の隅々まで付着している石綿を容易に剥離し且つ剥離された石綿の飛散を防止することにより、石綿の除去作業を安全で効率的に行うことができる吹付けアスベスト又は石綿含有吹付けロックウールの除去方法を提供することを目的とし、石綿の飛散防止を図るため作業場所を隔離する養生工程と、石綿を剥離して取り除く除去工程と、除去した石綿及び石綿を含んだ廃棄物を処理する処理工程とからなる吹付けアスベスト又は石綿含有吹付けロックウールの除去方法において、前記除去工程は、圧縮エアと高圧水の混気ジェット噴流による直接洗浄を行う剥離手段によって建築物の建材の隅々まで付着している石綿を剥離すると共に、隔離養生内を噴霧状態にして剥離された石綿と噴霧水滴とが混じり合って落下し泥状となって石綿の飛散を防止することを特徴とする「吹付けアスベスト又は石綿含有吹付けロックウールの除去方法」が提案されている。 On the other hand, as a cleaning method using a removing means that performs direct cleaning by a mixed jet jet of compressed air and high-pressure water developed by the present inventor, JP 2007-92387 A (Patent Document 2) Spraying asbestos or asbestos-containing spraying that can asbestos removal work safely and efficiently by easily peeling off asbestos adhering to every corner of building materials and preventing the scattered asbestos from scattering The purpose is to provide a method for removing rock wool. To prevent asbestos from being scattered, a curing process for isolating the work place, a removal process for peeling off asbestos, and a waste containing the removed asbestos and asbestos. In the method of removing sprayed asbestos or asbestos-containing sprayed rock wool comprising a processing step to be processed, the removing step is a direct washing by a mixed jet jet of compressed air and high-pressure water. The asbestos adhering to every corner of the building materials of the building is peeled off by the peeling means to perform, and the separated asbestos and the sprayed water droplets are mixed with each other and fall into a mud. A “method for removing sprayed asbestos or sprayed rock wool containing asbestos”, which is characterized by preventing the scattering of asbestos, has been proposed.
上記発明によれば、圧縮エアと高圧水の混気ジェット噴流による直接洗浄を行う剥離手段によって建築物の建材の隅々まで付着している石綿を剥離し、隔離養生内を噴霧状態にして剥離された石綿と噴霧水滴とが混じり合って落下し泥状となって石綿の飛散を防止することから、従来の除去方法と比べて石綿の除去作業を安全で効率的に行うことが可能になる。 According to the above invention, the asbestos adhering to every corner of the building material of the building is peeled off by the peeling means that performs direct cleaning by the mixed jet jet of compressed air and high-pressure water, and the isolated curing interior is sprayed and peeled off.
